age Modern File Encryption Tool skillA
age Modern File Encryption Tool is agent-read markdown (skill) from agentskillexchange/skills: Encrypt and decrypt files with age (FiloSottile/age), a simple, modern encryption tool with small explicit keys, post-quantum support, no config options, and UNIX-style composability. A practical replacement for GPG in most workflows..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add agentskillexchange/skills/age Modern File Encryption Tool@git:20260710.62afd0fmdr add agentskillexchange/skills/age Modern File Encryption Tool@sha256:73effe94e38b0f83Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
